The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Rowridge (Isle Of Wight, England) mast?

Julia Behn - I'd call the management company (if there is one) and get them to send someone round to sort out the communal aerial. I did this a few years ago when I lived in a flat. The costs gets split equally between all leaseholders! Also, make sure they put the aerial on vertical alignment if pointing at Rowridge.

Despite clearing my channels both on my Freeview box & also on my digital tv & retuning both sets either I find I am missing channels or they pixelate or once found the channels are lost. Sky News, Channel 5, E4, E4+1, 5* & 5USA are the most ellusive.
My tv aerial points south to Rowridge.
What can I do to receive all channels, retain them & overcome the pixelation?

Shirl,Southampton.Switching the polarity of your aerial from horizontal to vertical is a start as the SDN,ArqA and ArqB commercial multiplexes from Rowridge only transmit 50kw in horizontal mode but 200kw in vertical mode.The reason for this dual polarity is that the SDN,ArqA and ArqB multiplexes from Rowridge on frequencies 25,22 and 28 respectively clash exactly with the 200kw horizontally powered commercial SDN,ArqA and ArqB multiplexes from Crystal Palace transmitter also on frequencies 25,22 and 28 respectively there.Hence the horizontally polarised 50kw SDN,ArqA and ArqB muxs from Rowridge are overpowered by the 200kw horizontally polarised SDN,ArqA and ArqB muxs from Crystal Palace and instead a 200kw vertically polarised equivalent to offset this problem on Rowridge was implemented and alleviates this difficulty as such !

Seem to have fixed the problem. Read that rotating my aerial from horizontal polarisation to vertical could do the trick. Since its easy as its in the loft (and no cost!) I tried it yesterday. Last night was the first time since the first retune for Rowridge that WE HAD NO PROBLEMS!

Phil Alcock.Pleased that the problem that you had has now been alleviated by switching aerial polarity from horizontal to vertical especially concerning the commercial SDN,ArqA and ArqB multiplexes on Rowridge.

Hi
During the past week reception from ITV1, C4 etc has been eratic - no signal daytime, a bit better at night. Was originally OK but, despite re-tuning, now not good. Could this be due to sunspot activity? Aerial is clear of roof ridge and points same direction as neighbours aerials. Aerial is high-gain & has preamp on-board. Is this a polarisation problem? 4th May 2012

R W Penny,Arundel.Is your aerial horizontal or vertical polarisation and if so is it a group A type (tipped red) or a group W wideband type (tipped black).Polarisation could be a problem,but so could the preamp you mentioned on board as well as the aerial being a group W wideband type some 60 odd miles from your location to Rowridge,and possibly the condition of both your aerial co-ax cable and co-ax aerial plug too.If you leave a full post code preferably to ascertain the possibility of a single frequency interference issue on frequency 27 in your location,the D3+4 multiplex on Rowridge you claim has been erratic just recently,or possible inversion but highly unlikely then further assistance will be available to you.
